JOHN J. STEVENSON, OF AUBURN, NEW YORK.

IMPROVEMENT IN LUBRICATINGJOURNALS.

Specification forming part of Letters Patent No. 55,386, dated June 5, 1866 antedated May 22, 1866.

To all whom it may concern:

Be it known that I, J. J. STEVENSON, ofthe city of Auburn, in the county of Cayuga and State ot' New York, have invented a new and useful Improvement in. Mowing` and Reapin g Machines; and I do hereby declare the following is a full, clear, and exact description ofthe same, reference being` had to the accompanying drawings, and to the letters ot' reference marked thereon, making part of this specilication, in which- Figure l is a perspective View; Fig. 2, a vertical section taken through Fig. 1 in the center of the oil-box.

lhe object ot' this invention is to provide some easy and practical method of oiling the bearings, many ot' which in every mowing and reaping machine are liable to become dry, and/when in that state, and before the operator is aware of it, the box or bearing, and perhaps both, are badly injured, if not rendered wholly unfit for use, by the abrasion or cutting of the one upon the other. This formidable rdit'liculty presents itself much more in this kind of machine than any other-the great amount ot' dust and gritty matter aoat in the atmosphere underneath, through, and above the machine licks up the oil and absorbs everything in a duid state with which it comes in contact. Now, in order to remove this difficulty I have applied to the boxes of' the mowing;l and reaping machines the selt'- oiling box, and the application of the above box to the above machines will and does constitute the sum and essence of my invention.

And in order that others skilled in the art may make and use my invention, l will proceed to describe its construction and mode of operation.

In Fig. 1, A is the oil-cup,- and G the box, both being cast ot' one piece of metal, and B the shaft. The oil-cup A is lled with cotton, or cotton-waste, or other iibrous material insertedintoitthrough tl'ieopeningatD, Iand then oil poured upon it until it becomes saturated therewith. rIhe cover E is then turned over the opening, and all dust or tioating particles ot' matter is thereby excluded from the cup.

Fig. 2 is a vertical section ot' the above, taken through the center ofthe oil-cup. rJhe space F, Fig. 2, is the inside of the oilcup; B, the shaft, G, the box, and A the oil-cup.

When the space is tlled as above described, said'oiled cotton or waste will come in contact with the shaft at G, and as the shaft is rotated it will draw the oil out ofthe saturated fibrous material and keep theshaft constantly and abundantly lubricated.

Now, I am aware that there has been a pat-- ent taken t'or a self-oiling box applied to the crank-pin of mowing and reaping machines, and I do not wish or intend to make this use of my invention; but

What I claim as new, and wish to secure by Letters Patent, is-

The application of the seltoiling cup or box to the bearings ot' mowing and reaping' machines, when used as and for the purpose above specified.

JOHN J. STEVENSON.
